Experimental Investigations of Force Character of Extra Vehicular Activity Glove in Different Pressure Levels

摘要

This article researches the force characters of the Extra Vehicular Activity (EVA) glove under different pressure conditions using an ergonomic experimental method. First, 20 male subjects are selected to operate a series of operation actions with their bare hands. Some typical operation actions, such as hold, screw and pinch, are requested to collect the force data of these subjects. Second, these subjects are asked to repeat these operation actions above again when they wear the EVA glove under the different pressure level. Finally, we use some correlation analysis techniques to mine the relationship among the collected data of different pressure levels and different wearing states. Experiment results show us: the force data of bare hand state have a correlation with the force data of wearing EVA glove state. So, this result can be use to analyze and estimate the force size of the wearing EVA glove state when the astronauts work in the space station.
